DISINFECTING AND AUTOMATIC FLUSH-TANK.

SPECIFICATION forming part of Letters Patent No. 243,970, dated July 5,1881. Application filed April 8, 1881. (No model.)

To all whom it may concern: 7

Beit known that I, JAMES J. Pownns, of Brooklyn, in the county of Kingsand State of New York, have invented a new and Improved Disinfecting andAutomatic Flush-Tank, of which the following is a full, clear, and exactdescription.

The object of my invention is to facilitate collecting and disinfecting.liquid sewage and removing it after disinfection.

The invention relates to a tank arranged at or below the end of a sewer,or of any conduit through which a liquid is passed. The foul liquid maybe pumped, or flow, or be conducted in any suitable manner to the tank.

The invention consists in a tank provided with a siphon, the inner endof which is closed by a valve on a pivoted lever, to the outer end ofwhich a float with a vertical tubular extension is attached, whereby thefloat will be raised as the level of the water rises, thus closing thesiphon; but when the water-level has reached the upper edge of thetubular extension of the float the water will flow into the float,causing it to descend, thereby opening the siphon and permitting thewater to flow from the tank, the water in the float flowing off througha small flexible tube.

The invention further consists in a tank for the liquid disinfectant,which tank is provided with a spring-valve combined with a float, sothat when the float rises the supply-pipe of this disinfectant-tank willbe closed by the spring-valve, and a moment later a weighted valveclosing a port in the bottom of the disinfectant-tank will be opened bya lever connected with the lever of the float, thus permitting thedisinfectant to flow through this port into and mix with thesewage-liquid, thereby disinfecting the same.

In the accompanying drawings, Figure 1 is a cross-sectional elevation ofmy improved disinfecting and automatic flush-tank. Fig. 2 is a detailside elevation of the front end of the spring-valve of the tankcontaining the disinfectant.

A siphon-tube, A, enters into the lower part of the tank B, the innerend of this siphon being a short distance above the bottom of the tank.A lever, O, is pivoted to a short arm, D, of the end of the siphon-tube,and on the upper edge of this lever O a block, E, of rubber, wood,metal, earthenware, &c., is fastened in such a manner that it fits inand over the end of the siphon-tube, thus closing it when the lever O israised. The outer end of the lever O is connected with a float, F, by arod, G, of

such length that the float will be below the curve H of the siphon-tube,so that the float will be raised before the level of the water riseshigh enough to permit the siphon to 0p crate. This float F is providedwith a vertical tubular extension, J, of such length that its upper edgeis on a level with the height to which the tank B is to be filled beforebeing discharged. This extension-tube J is guided by the rings K of anupright, L. The float F is connected with the outer arm of thesiphontube A by a flexible tube, F.

A vessel or tank, M, for the liquid disinfectant, is arranged in theupper part of the tank B, and is connected with thedisinfectant-reservoir by a pipe, N, which passes through it and into avalve-casing, 0, connected with the vessel M by a pipe, P, andcontaining avalve, Q, fitting against the end of the pipe N, and pressedagainst the same by a spiral spring, R, surrounding the valve-stem S,which is provided at the outer end with a longitudinal slot,

T, into which a cam, U, of a lever, V, passes,

pivoted to an arm, W, of the casing O.

A float, X, is attached to the outer end of the lever V, and this leverV is connected by a chain or cord, Y, with a lever, Z, pivoted to thebottom of the vessel M. A weighted block or valve, I, closes a port, a,in the bottom of the vessel M, and is provided with a stud, b,projecting through the port a. The lever V is of such length that thefloat X will rise about six inches before the level of the water risesto the line at as, so that the disinfectant will be thoroughly mixedwith the liquid sewage before the same is discharged.

The operation is asfollows: Theliquid sewage is conducted into the tankB in some suitable manner, and as its level rises it raises the float F,thereby closing the inner end of the siphontube A. When the level of theliquid arrives within about six inches from the line a: w it raises thefloat X, causing the cam U to move in the direction of the arrow a inthe slot T, Fig. 2, thus permitting the spring B to force the valve Qagainst the end of the pipe N, and thus shutting off the supply ofdisinfectingliquid from the disinfectant reservoir. The float stillrises, and as it raises the end of the lever Z by means of the chain Ythis lever strikes the stud b and raises the valve I, permittin g thedisinfecting-liquid in the vessel M to flow from the same and mix withthe sewage-liquid, thereby disinfecting the latter; but by this time thelevel of the sewage-liquid has reached the line 0000, and flows down thetubular extension J into the float F, causing the same todescend,whereby theinner end of the siphontube-A is opened, permittin gthe sewage-liquid to flow off through the siphon-tube. The sewage-liquidin the float F then flows oif through the flexible tube F, leading intothe outer part of the siphon-tube A, thus restoring the buoyancy of thefloat. As soon as the level of the sewage-liquid descends the float Xand the lever Z descend also, whereby the valve I descends, closing theaperture or port a, and the cam U moves in the reverse direction of thearrow (0', thus opening the end of the pipe N, and permittingdisinfecting-fluid to flow from the reservoir, through the pipe N,casing O,

, and pipe P, into the vessel M. As the end of the pipe N is closedbefore the valve Iis raised, the quantity of disinfecting-fluid in thevessel M only will flow into the tank B, and all waste of thedisinfecting-fluid is avoided.

The length of the inner arm of the siphontube is entirely independent ofthe height of the tank, or of the height of the level to which theliquid sewage rises, and the inner arm of the siphon can thus be mademuch shorter than in the siphon made heretofore.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combinatiomwith asewage-liquid-eollecting tank, of adisinfectant-vessel and automatically-operatin g devices, substantiallyas described, for discharging the contents of this disinfectant-vesselinto the tank, substantially as herein shown and described, and for thepurpose set forth. I

2. The combination,with asewage-liquid-collecting tank, of adischarge-siphon, of a disinfectant-vessel, and ofautomatically-operatin g devices, substantially as described, fordischarging the contents of this disinfectant-ms sel into the tank,substantially as herein shown and described, and for the purpose setforth.

3. In an automatic flush-tank, thecombination, with the siphon-tube A,of the valve E, the lever O, and the float F, provided with anextension, J, and a discharge-tube, F, substan tially as herein shownand described, and for the purpose set forth.

4.
